Anxiety and the Need for Certainty: Learning to Live With “I Don’t Know”

If you struggle with anxiety, you probably know this feeling:

You just want to know.

You want to know what’s going to happen.
You want to know what someone meant by that text.
You want to know if you made the right decision.
You want to know whether things are going to work out.
You want to know that everything is going to be okay.

And honestly? I get it. Uncertainty is uncomfortable. And when you already tend to overthink, uncertainty can feel almost unbearable. Your brain starts looking for answers.

What if something goes wrong?
What if I made the wrong choice?
What if they’re upset with me?
What if this doesn’t work out?
What if I missed something?

So you think about it some more.

Then you replay the conversation.

Maybe you ask a friend what they think.

Maybe you Google it.

Maybe you check your phone again.

Maybe you try to come up with every possible scenario so you're prepared for whatever happens.

And for a moment, you feel a little better.

Until the anxiety comes back with another question.

Welcome to the exhausting world of trying to get certainty from an uncertain world.

Anxiety Doesn't Like "I Don't Know"

Anxiety wants answers because answers feel safe. Answers feel like control.

If I know what's going to happen, I can prepare for it.

If I know what someone is thinking, I can respond appropriately.

If I know I've made the right decision, I don't have to worry about regretting it.

If I know everything is going to be okay, I can finally relax.

Makes sense, right?

Except there’s a problem. We can't know everything.

No matter how much you think, analyze, research, plan, prepare, or ask for reassurance, there will always be things you simply cannot know.

And this is where anxiety can really get you stuck. Because instead of accepting "I don't know," your brain keeps trying to turn it into "I need to figure this out." Your brain keeps trying to find ways to feel in control.

When Thinking Stops Being Helpful

Thinking isn't the problem. Thinking can actually be really helpful.

You need to think through decisions. You need to consider consequences. You need to plan. You need to problem-solve.

The problem is when thinking stops being problem-solving and starts becoming rumination.

There’s a difference.

If you're trying to figure out how to have a difficult conversation with your partner, that's problem-solving.

If you've spent two hours replaying a conversation you already had, analyzing every word you said, wondering what their facial expression meant, and trying to determine whether they're secretly angry with you...

That's ruminating and that’s when anxiety is talking.

And unfortunately, anxiety is really good at convincing you that one more round of thinking will finally give you the answer.

It usually doesn't. It just gives you another question.

The Reassurance Trap

One of the ways we try to manage uncertainty is through reassurance.

"Do you think I'm overreacting?"

"Do you think they're mad at me?"

"Are you sure this is going to be okay?"

"What would you do?"

There's nothing wrong with asking someone for support. We all need reassurance sometimes.

But if you notice that you need reassurance over and over again before you can feel okay, it may actually be keeping your anxiety going.

You get reassurance. You feel better. Then the doubt creeps back in. So you ask again. And eventually your brain learns:

"I can't tolerate uncertainty unless someone else tells me I'm okay."

That's a pretty miserable way to live.

And it doesn't build confidence.

The Goal Isn't to Feel Certain

This is one of the hardest things to understand about anxiety:

The goal isn't to get rid of uncertainty. Because you can't.

The goal is to become more comfortable with it. Instead of: “I need to know this is going to work out."

Try: "I don't know how this is going to work out, but I trust myself to deal with whatever happens."

Instead of: “I need to know whether they are upset with me."

Try: "I don't know what they're thinking. If there's something I need to know, I can ask."

Instead of: "I need to know that I made the right decision."

Try: “I made the best decision I could with the information I had at the time."

Notice the difference.

You're not telling yourself that everything will be fine.

You're not pretending that nothing bad could happen.

You're reminding yourself that you can handle not knowing. That's a very different kind of confidence.

What If Something Goes Wrong?

Here's where anxiety usually pushes back.

"But what if something DOES go wrong?"

It might.

I know. That's not the comforting answer anxiety wants.

But sometimes things don't work out.

Sometimes people disappoint us.

Sometimes we make decisions we later realize weren't the best ones.

Sometimes relationships end.

Sometimes plans change.

Sometimes life just throws something at us that we didn't see coming.

And you know what? You figure it out.

Maybe it sucks. Maybe you cry. Maybe you need help. Maybe you have to change course. But you figure it out.

You don't need to know today exactly how you're going to handle something that hasn't even happened yet.

You just need to trust that you'll handle it when you get there.

Learning to Sit With the "What If"

This is where anxiety treatment can get uncomfortable.

Because instead of immediately trying to answer every what if, you start practicing allowing the question to exist without solving it.

"What if they don't like me?"

Maybe they don't.

"What if I make the wrong decision?"

Maybe you do.

"What if this doesn't work out?"

Maybe it won't.

And then:

"And I'll deal with it if it happens."

That last part is important.

You're not trying to convince yourself that your feared outcome won't happen.

You're reminding yourself that you don't have to solve a problem that hasn't happened yet.

You Don't Have to Be 100% Sure

I work with a lot of people who feel like they need to be completely certain before making a decision.

They want to know they're making the right choice.

But most decisions don't come with a giant neon sign telling you:

THIS IS DEFINITELY THE RIGHT ANSWER.

Sometimes you have enough information to make a reasonable decision.

That's it.

You make the decision.

You move forward.

And you adjust if you need to.

That's life.

And honestly, learning to tolerate that can be incredibly freeing.

Try Asking Yourself These Questions

The next time you notice yourself getting caught in an uncertainty spiral, stop and ask:

Am I actually solving a problem right now, or am I trying to get certainty?

Is there something I can realistically do about this right now?

Am I looking for information—or reassurance?

What would happen if I didn't answer this question right now?

And perhaps the most important one:

Can I allow myself to not know?

You may not feel comfortable.

That's okay.The goal isn't immediate comfort.

The goal is learning that discomfort doesn't mean you have to do something about it.

"I Don't Know" Can Be Enough

I know that "I don't know" can feel scary when you're anxious.

But what if it didn't have to mean something was wrong?

What if "I don't know" simply meant:

I don't have all the information yet.

I can't control this.

I don't know what someone else is thinking.

The future hasn't happened yet.

I don't have to make this decision today.

I can handle uncertainty.

I'll figure it out when I get there.

Because the truth is, you will never be able to eliminate uncertainty from your life.

There will always be unanswered questions.

There will always be things outside your control.

There will always be situations where you have to take a step forward without knowing exactly where the road leads.

And maybe the goal isn't to become someone who never feels uncertain.

Maybe the goal is to become someone who can say:

"I don't know. And I'm going to be okay anyway. I’m going to work it out. I always do.”

That's not giving up control.

That's learning to trust yourself.
